Findings could lead to use of calorie-free caffeinated drinks to cut obesity and type 2 diabetes – but more research needed
Having high levels of caffeine in your blood may lower the amount of body fat you carry and reduce the risk of type 2 diabetes, research suggests.
The findings could lead to calorie-free caffeinated drinks being used to reduce obesity and type 2 diabetes, though further research is required, the researchers wrote in the BMJ Medicine journal.
Dr Katarina Kos, a senior lecturer in diabetes and obesity at the University of Exeter, said the research showed potential health benefits for people with high levels of caffeine their blood, but added: “It does not study or recommend drinking more coffee, which was not the purpose of this research.”
She said any caffeinated drinks containing sugar and fat would offset the positive effects.
The researchers said their work built on previously published research, which suggested that drinking three to five daily cups of coffee, containing an average 70-150mg of caffeine, was associated with a lower risk of type 2 diabetes and cardiovascular disease.
As those were observational studies, they made it difficult to pinpoint whether the effects were because of caffeine or other compounds, the researchers said.
This latest study used a technique known as Mendelian randomisation, which establishes cause and effect through genetic evidence. The team found two common gene variants associated with the speed of caffeine metabolism, and used these to work out genetically predicted blood caffeine levels and whether this was associated with lower BMI and body fat.
